Background Selections of the Pale and Melanic Forms of the Cryptic Moth, Phigalia titea (Cramer)
Abstract
KETTLEWELL1 demonstrated that the pale (typical) and melanic (carbonaria) forms of the peppered moth, Biston betularia L., tend to rest on white and black backgrounds respectively, when presented with a choice between the two. I wish to summarize results obtained in a similar experiment, using typical and melanic individuals of the North American geometrid, Phigalia titea.
